Hi, I am really starting late and cannot do a review course. I was wondering what anyone who isn't taking a review course is using to review the material for the exam. I heard the Lindeburg book has a lot more material than needed and that the level of difficulty is much higher than the actual exam. Thanks! Or if people taking the review course guide me to which sections to look through in the Lindeburg book. I also have the Intro to Environmental Engineering by Davis and Cornwell, Air Quality by Cooper and have ordered a used copy of Lagrega for Haz waste.
